Wacker Powersil® 466 A/B Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	POWERSIL® 466 A/B is a liquid silicone rubber with medium conductivity, stable electrical properties and good mechanical properties. Special features: high elongation at break, low tension set stable electrical properties good mechanical properties ready-to-use, two-component system Application: POWERSIL® 466 A/B is suitable for production of electrically conductive injection molded articles, especially cable accessories in the medium and high voltage range. The range of use spreads from push-on accessories to cold shrink applications. POWERSIL® 466 A/B combines a low Shore A Durometer with high elongation, good setting properties (low tension set) and good mechanical properties which are a must for cold shrink applications.
